Effect of Indole-3-Acetic Acid (IAA) on biomass production of oyster mushroom (Pleurotus sajor-caju)

Abstract

Biomass parameters (mycelia diameter, weight and protein content) of oyster mushroom (Pleurotus sajor-caju) from Kota Kinabalu, Sabah were studied using Indole-3-Acetic Acid (IAA) treatments method. There were no significant differences (P>0.05) in terms of mycelia weight and protein content corresponding to different concentration of 1M treatments. Despite no significant difference, but treatment with 5 mg/L of 1M concentration give relatively, a maximum increase in mycelia diameter and protein content. The higher concentration of IAA treatment gives the most enhancements in increasing cell wall plasticity so as a better regulation of specific protein synthesis. These results warrant further study and analysis still need to be carried out in order to Improve understanding on the effectiveness and economical
concerns on the usage and application of IAA as a naturally occurring plant hormone in oyster mushroom production.
